[Numpy-discussion] dtype=object behavior change from 0.9.6 to beta 1

In version 0.9.6 one used to be able to do this:

In [4]: numpy.__version__
Out[4]: '0.9.6'


In [6]: numpy.array([numpy.array([4,5,6]), numpy.array([1,2,3])],
dtype=object).shape
Out[6]: (2, 3)


In beta 1 numpy.PyObject no longer exists.  I was trying to get the
same behavior with dtype=object but it doesn't work:

In [7]: numpy.__version__
Out[7]: '1.0b1'

In [8]: numpy.array([numpy.array([4,5,6]), numpy.array([1,2,3])],
dtype=object).shape
Out[8]: (2,)


Is this an intentional change?
